Hello,
I did a newbie mistake today. I was under the PH helm cleaning and adjusting the cables. I was trying to fix the symptom where the throttle arm will move up and accelerate but sags right back down almost immediately. Byt that's anotber issue. In the process the tip of a cable got away from me and short circuited the shutdown button and it stopped working. The shutdown in the engine room still works fine.

I am assuming that there is a fuse somewhere that needs replacing. The glass fuses nearest the shutdown button all look fine. Could the fuse be located in the silver electric box in the engine room? Thought I would ask the forum, hoping that I don't need a new shutdown relay.

Thank you in advance.

In the big DCv box near that engine.
 
on my 1977 46sf the fuse was behind a plastic cover in the engine room. white plastic about 4 inches wide and 8 inches tall held to bulkhead with 4 screws
 
Mine are inline near the actual solenoid.
 
Thank you kindly for the comments. Much appreciated..The inline fuses seem to be OK, I opened the DCV box near the engine and found a 20A ceramic glass-type fuse with Shutdown under it.. cannot tell if it's blown.. the Start fuse next to it looks just the same. I will order a new one regardless.
But what is interesting is that the Stop button in the engine room still works as usual. I guess they have separate fuses.
 
Test the fuse for continuity with a multimeter.
 
There’s an adjustment on your motor that has a large spring in it. If you tighten that up, it will stop the throttle from creeping back. You need to do it while the motor is running and it’s a two-man job one tightening and one at the helm and have the boat underway to get it to be perfect.
